ABSTRACT:
A ship loading ramp designed to allow for substantial changes in tide. The ramp pivots about a pair of lugs at each end. Each lug extends from one corner of the ramp into a fitting having an upward opening slot. One set of slotted fittings is in a tailpiece on the pier, and the second set of slotted fittings is located on the deck of the ship. As the level of the ship deck falls below the level of the pier the ramp will settle on the pier and lift out of the slotted fittings on the ship deck, thereby freeing the ramp from the ship. As the ship later rises with the tide, the slotted fittings on the ship will engage the lugs on the ramp and will proceed to raise and tilt the ramp. During this period of rising tide, the ramp will become further and further inclined until it reaches a maximum positive angle of inclination. At this maximum angle, a pair of cables extending from the ship to the ramp will pull taut and proceed to lift the ramp out of the slotted fittings on the tailpiece and into the air. As the ship later falls with the tide, the lugs on the ramp will engage the slotted fittings in the tailpiece, and the ramp will be usable again.
